CVE-2026-17509
MediumCVSS 6.5Summary
The WPML Multilingual CMS plugin for WordPress is vulnerable to time-based SQL Injection via the 'elementIds' parameter in all versions up to and including 4.9.5 due to insufficient escaping and lack of preparation on the SQL query. This allows authenticated attackers with Subscriber-level access and above to append additional SQL queries to extract sensitive information from the database. The vulnerability is exploitable due to an authorization bypass where the registered authorization callback fails to execute, allowing any authenticated user to access administrative translation functionalities.
Risk Assessment
An attacker can extract sensitive data from the database, such as passwords, user data, or content. This may lead to confidentiality and integrity breaches and potential admin account takeover.
Recommendation
Update the WPML plugin to the latest patched version immediately. Also, restrict user privileges and monitor database queries.

Original NVD description (English source)
The WPML Multilingual CMS plugin for WordPress is vulnerable to time-based SQL Injection via the ‘elementIds’ parameter in all versions up to, and including, 4.9.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This vulnerability is exploitable due to an authorization bypass where the registered authorization callback fails to execute, allowing any authenticated user regardless of role to access administrative translation functionalities.
